The Coronavirus Dashboard: the case of India
This Coronavirus dashboard: the case of India provides an overview of the 2019 Novel Coronavirus COVID-19 (2019-nCoV) epidemic for India. This dashboard is built with R using the R Makrdown framework and was adapted from this dashboard by Rami Krispin.
Data
The input data for this dashboard is the dataset available from the {coronavirus} R package. Make sure to download the development version of the package to have the latest data:
install.packages("devtools")
devtools::install_github("RamiKrispin/coronavirus")
The data and dashboard are refreshed on a daily basis.
The raw data is pulled from the Johns Hopkins University Center for Systems Science and Engineering (JHU CCSE) Coronavirus repository.
Please understand that this is for educational puroposes. Please refer to your local health authority for the most updated and accurate guidelines.
